  1. Lesson 10-Basic Software Tools

  2. Overview • Text-based editing tools. • Graphical tools. • Sound editing tools. • Animation, video, and digital movie tools. • Video formats. • Utilities useful for multimedia.

  3. Text-based Editing Tools Word processors: • Are powerful applications that include spell checkers, table formatters, thesaurus, and pre-built templates for commonly used documents. • Are used for creating project letters, invoices, and storyboards. • Allow embedded multimedia elements.

  4. Text-based Editing Tools Word processors (continued): • Microsoft Word and WordPerfect are Word processors. • Often come bundled in an "Office Suite."

  5. Text-based Editing Tools Optical Character Recognition (OCR) software: • Converts bitmapped characters into electronically recognizable ASCII text. • Makes use of probability and expert system algorithms. • Is very accurate and saves time and effort.

  6. Graphical Tools • Painting and drawing tools. • 3-D modeling tools. • Image editing tools.

  7. Painting and Drawing Tools • Most graphic programs use bitmapped images since they provide the greatest choice. • Include the Eyedropper tool, Autotrace tool, and anti-aliasing, airbrushing, blending, and masking functionalities. • PhotoShop, Fireworks, and Painter are painting software. • CorelDraw, FreeHand, and Illustrator are drawing software.

  8. Painting and Drawing Tools Features include: • An intuitive graphical user interface. • Scalable dimensions. • Multiple undo capability. • Scalable text font support. • Support for third-party special effect plug-ins. • Layering capability.

  9. 3-D Modeling Tools Features include (continued): • Good color and palette management. • Multiple dimension windows and unlimited cameras. • Lathe and extrude features. • Ability to drag and drop primitive shapes, sculpt organic objects. • Color and texture mapping.

  10. Image-Editing Tools • Are specialized and powerful tools for enhancing and retouching existing bitmapped images. • Features include conversion of image-data types and file formats, masking features, employment of virtual memory scheme, etc. • Support third-party plug-ins.

  11. Sound Editing Tools • Enables the user to see music as well as hear sound. • This is done by drawing a representation of sound in fine increments. • Enable the user to create custom system beeps. • System beeps are pre-packaged sounds that indicate an error, warning or special user activity.

  12. Animation, Video, and Digital Movie Tools • Animation is a sequence of bitmapped graphic scenes or frames, rapidly played back. • Animations can be made within some authoring systems by moving objects or sprites to simulate motion. • Moviemaking tools take advantage of QuickTime and AVI formats to create, edit, and present digitized motion video segments.

  13. Animation, Video, and Digital Movie Tools • Digital video editing and playback require a large amount of free disk space. • When working with digital video, it is necessary to defragment and optimize the disk before recording and playing back movie files. • It is necessary to compress movie files before delivery.

  14. Animation, Video, and Digital Movie Tools • Compression ratio is the size of the original image divided by the size of the compressed image. • Compression can by lossy or lossless. • Lossy schemes ignore picture information the viewer may not miss. • Lossless schemes preserve the original data precisely.

  15. Video Formats QuickTime: • Is a software-based architecture for integrating sound, text, animation, and video on Macintosh and Windows platform. • Is an extensible system for multimedia delivery. • Can deliver 3-D animations, virtual reality, and streaming audio-video on the Web. • The three QuickTime elements are Movie file format, Media Abstraction Layer, and Media services.

  16. Video Formats QuickTime (continued): • Includes built-in support for ten different media types. • Offers a comprehensive set of services. • Allows embedded commands in HTML documents.

  17. Video Formats Audio Video Interleaved (AVI): • Is a Microsoft-developed format for playing full-motion interleaved video and audio sequences in Windows. • Does not require specialized hardware. • Is an inextensible, open environment. • Lacks serious video editing features. • The OpenDML format was developed to make AVI more functional.

  18. Video Formats • QuickTime and Audio Video Interleaved (AVI) formats support special algorithms, provide a methodology for interleaving, and allow organized streaming of data from disk into memory. • Digital Versatile Disc (DVD) is a hardware format that uses laser light to store and read digital information.

  19. Utilities Useful For Multimedia • Screen-grabber - Enables the user to move bitmapped images by placing them on the clipboard. • Format converters - Useful for projects where the source material originates on different platforms.

  20. Summary • Word processors and OCR software are used to handle text in multimedia. • Painting and drawing tools, 3-D modeling tools, and image editing tools manipulate the graphical content of the project. • QuickTime for Macintosh and AVI for Windows are the two most widely used video formats.
